Ground-based navaids and aircraft equipment are not to be installed and/or functioning when conducting an overlay approach (unless AFM requires it)
GNSS overlay approaches don't exist over LOC-based approaches.

There is none, each station has its frequency and there is no common one.
44
What does NOT ASSESSED mean on a departure procedure?
It means that the IFR departure hasn't been assessed for obstacle clearance.
PIC is therefore responsible for determining climb gradients and routings for obstacle clearance and terrain avoidance.
